BACKGROUND 1. Technical Field

The present disclosure relates to a semiconductor package device and a method of manufacturing the same, and more particularly, to a semiconductor package device including a shielding layer and a method of manufacturing the same.

2. Description of the Related Art

Semiconductor devices have become progressively more complex, driven at least in part by the demand for enhanced processing speeds and smaller sizes. Enhanced processing speeds tend to involve higher clock speeds, which can involve more frequent transitions between signal levels, which, in turn, can lead to a higher level of electromagnetic emissions at higher frequencies or shorter wavelengths. Electromagnetic emissions can radiate from a source semiconductor device, and can be incident upon neighboring semiconductor devices. If the level of electromagnetic emissions at a neighboring semiconductor device is sufficiently high, these emissions can adversely affect the operation of the neighboring semiconductor device. This phenomenon is sometimes referred to as electromagnetic interference (EMI). Smaller sized semiconductor devices can exacerbate EMI by providing a higher density of semiconductor devices within an overall electronic system, and, thus, a higher level of undesired electromagnetic emissions at neighboring semiconductor devices.

One way to reduce EMI is to shield a set of semiconductor devices within a semiconductor package device. In particular, shielding can be accomplished by including an electrically conductive casing or housing that is electrically grounded and is secured to an exterior of the package. When electromagnetic emissions from an interior of the package strike an inner surface of the casing, at least a portion of these emissions can be electrically shorted, thereby reducing the level of emissions that can pass through the casing and adversely affect neighboring semiconductor devices. Similarly, when electromagnetic emissions from a neighboring semiconductor device strike an outer surface of the casing, a similar electrical shorting can occur to reduce EMI of semiconductor devices within the package.

DETAILED DESCRIPTION

FIG. 1 illustrates a cross-sectional view of a semiconductor package device 1 in accordance with some embodiments of the present disclosure. The semiconductor package device 1 includes a substrate 10, passive components 11 a, 11 b, an active component 12, package bodies 13, 14 and a shielding layer 15. In some embodiments, the package body 13 is referred to as a first package body 13 and the package body 14 is referred to as a second package body 14. In some embodiments, a package body includes a first portion 13 of the package body and a second portion 14 of the package body.

The substrate 10 may be, for example, a printed circuit board, such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass-fiber-based copper foil laminate. The substrate 10 may include an interconnection structure, such as a redistribution layer (RDL) or a grounding element. In some embodiments, the grounding element is a via exposed from a lateral surface 102 of the substrate 10. In some embodiments, the grounding element is a metal layer exposed from the lateral surface 102 of the substrate 10. In some embodiments, the grounding element is a metal trace exposed from the lateral surface 102 of the substrate 10.

The passive components 11 a, 11 b are disposed on a top surface 101 of the substrate 10. The passive component 11 a, 11 b may be an electronic component, such as a capacitor, a resistor or an inductor. Each passive component 11 a, 11 b may be electrically connected to one or more of another passive component 11 a, 11 b and to the substrate 10 (e.g., to the RDL), and electrical connection may be attained by way of Surface Mount Technology (SMT).

The active component 12 is disposed on the top surface 101 of the substrate 10. The active component 12 may be an electronic component, such as an integrated circuit (IC) chip or a die. The active component 12 may be electrically connected to one or more of the passive components 11 a, 11 b and to the substrate 10 (e.g., to the RDL), and electrical connection may be attained by way of flip-chip or wire-bond techniques. In some embodiments, a height of the active component 12 measured from the top surface 101 of the substrate is greater than that of the passive components 11 a, 11 b. In some embodiments, the active component 12 is referred to as a first electronic component and the passive component 11 a and/or 11 b is referred to as a second electronic component.

The package body 13 is disposed on the top surface 101 of the substrate 10 and encapsulates a part of the top surface 101 of the substrate 10, the passive components 11 a, 11 b and a part of the active component 12. A backside surface 121 (e.g., a top surface) of the active component 12 is exposed from the package body 13. In other words, the backside surface 121 of the active component 12 is aligned with a top surface 131 of the package body 13; for example, the backside surface 121 of the active component 12 is substantially coplanar with the top surface 131 of the package body 13. In some embodiments, the package body 13 covers the respective backside surfaces 111 a, 111 b (e.g., top surfaces) of the passive components 11 a, 11 b. A lateral surface 132 of the package body 13 is aligned with the lateral surface 102 of the substrate 10; for example, the lateral surface 132 of the package body 13 is substantially coplanar with the lateral surface 102 of the substrate 10. In some embodiments, the package body 13 includes an epoxy resin having fillers dispersed therein.

The package body 14 is disposed on a portion of the top surface 131 of the package body 13 and over the passive components 11 a, 11 b. The package body 14 is not disposed over the active component 12. In some embodiments, a distance from a top surface 141 of the package body 14 to the respective backside surfaces 111 a, 111 b (e.g., top surfaces) of the passive components 11 a, 11 b is in a range from about 50 micrometers (μm) to about 100 μm. A thickness of the package body 14 (e.g., a distance from the top surface 141 of the package body 14 to the top surface 131 of the package body 13) is determined according to a thickness difference between the active component 12 and the passive components 11 a, 11 b. In some embodiments, an area of the package body 14 is greater than an area of each of the passive components 11 a, 11 b. In some embodiments, the package body 14 comprises, or is formed from, a photosensitive material, such as a photopolymer resin. In some embodiments, the package body 14 and the package body 13 comprise a same material. Alternatively, the package body 14 and the package body 13 may comprise different materials. In some embodiments, the top surface 141 of the package body 14 is higher than the top surface 131 of the package body 13. For example, a first distance may be between the top surface 141 of the package body 14 and the top surface 101 of the substrate 10, and a second distance may be between the top surface 131 of the package body 13 and the top surface 101 of the substrate 10, and the first distance may be greater than the second distance.

The shielding layer 15 is disposed on the backside surface 121 of the active component 12 and on external surfaces of the package body 13 and the package body 14 to cover the package body 13, the package body 14, the active component 12 and the lateral surfaces 102 of the substrate 10. The shielding layer 15 is electrically connected to the grounding element of the substrate 10. In some embodiments, the shielding layer 15 is a conformal shield. In some embodiments, a thickness of the shielding layer 15 is substantially uniform. A bottom of the shielding layer 15 is aligned with a bottom surface 103 of the substrate 10; for example, the bottom of the shielding layer 15 is substantially coplanar with the bottom surface 103 of the substrate 10. In some embodiments, the shielding layer 15 is a conductive thin film, and may include, for example, aluminum (Al), copper (Cu), chromium (Cr), tin (Sn), gold (Au), silver (Ag), nickel (Ni) or stainless steel, or a mixture, an alloy, or other combination thereof. The shielding layer 15 may include a single conductive layer or multiple conductive layers. In some embodiments, the shielding layer 15 includes multiple conductive layers, and the multiple conductive layers may include a same material, or ones of the multiple conductive layers may include different materials, or each of the multiple conductive layers may include different materials from others of the multiple conductive layers. In some embodiments, each conductive layer of the shielding layer 15 has a thickness of up to about 200 μm, such as up to about 150 μm, up to about 100 μm, up to about 50 μm, up to about 10 μm, up to about 5 μm, up to about 1 μm, or up to about 500 nanometers (nm). In some embodiments, each conductive layer of the shielding layer 15 has a thickness of down to about 100 nm or less, down to about 50 nm or less, or down to about 10 nm or less. In some embodiments, the shielding layer 15 includes multiple conductive layers, and the different conductive layers may have different thicknesses. Since the shielding layer 15 is conformal to the package body 14 and the package body 13, the shielding layer 15 includes a portion disposed on the package body 14 and another portion disposed on the package body 13, and a top surface of the former portion of the shielding layer 15 is higher than a top surface of the latter portion of the shielding layer 15.

In some other semiconductor package devices, a distance from a top surface of a package body to electronic components (e.g., mold clearance) may be insufficient, and thus a shielding layer in the semiconductor package device may increase unwanted parasitic capacitance, which may in turn deteriorate the reliability and function of the semiconductor package device. In accordance with some embodiments of the present disclosure, for example as shown in FIG. 1, the package body 14 is disposed over the passive components 11 a, 11 b to increase the mold clearance, so as to reduce the parasitic capacitance effect. By reducing the parasitic capacitance effect, the accuracy of the passive components 11 a, 11 b may increase and then insertion loss and return loss of a filter formed by the passive components 11 a, 11 b may be well controlled.

FIG. 2 illustrates a cross-sectional view of a semiconductor package device 2 in accordance with some embodiments of the present disclosure. The semiconductor package device 2 includes a substrate 20, passive components 21 a, 21 b, an active component 22, a package body 23, a package body 24 and a shielding layer 25. In some embodiments, the package body 23 is referred to as a first package body 23 and the package body 24 is referred to as a second package body 24. In some embodiments, a package body includes a first portion 23 of the package body and a second portion 24 of the package body.

The substrate 20 may be, for example, a printed circuit board, such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass-fiber-based copper foil laminate. The substrate 20 may include an interconnection structure, such as an RDL or a grounding element. In some embodiments, the grounding element is a via exposed from a lateral surface 202 of the substrate 20. In some embodiments, the grounding element is a metal layer exposed from the lateral surface 202 of the substrate 20. In some embodiments, the grounding element is a metal trace exposed from the lateral surface 202 of the substrate 20.

The passive components 21 a, 21 b are disposed on a top surface 201 of the substrate 20. The passive component 21 a, 21 b may be an electronic component, such as a capacitor, a resistor or an inductor. Each passive component 21 a, 21 b may be electrically connected to one or more of another passive component 21 a, 21 b and to the substrate 20 (e.g., to the RDL), and electrical connection may be attained by way of SMT.

The active component 22 is disposed on the top surface 201 of the substrate 20. The active component 22 may be an electronic component, such as an IC chip or a die. The active component 22 may be electrically connected to one or more of the passive components 21 a, 21 b and to the substrate 20 (e.g., to the RDL), and electrical connection may be attained by way of flip-chip or wire-bond techniques. In some embodiments, a height of the active component 22 measured from the top surface 201 of the substrate 20 is less than that of at least one of the passive components 21 a, 21 b. In some embodiments, the active component 22 is referred to as a first electronic component and the passive component 21 a and/or 21 b is referred to as a second electronic component.

The package body 23 is disposed on the top surface 201 of the substrate 20 and encapsulates a part of the top surface 201 of the substrate 20, a part of the passive components 21 a, 21 b and the active component 22. In some embodiments, both respective backside surfaces 211 a, 211 b (e.g., top surfaces) of the passive components 21 a, 21 b are exposed from the package body 23. In some embodiments, a single one of the respective backside surfaces 211 a, 211 b of the passive components 21 a, 21 b is exposed from the package body 23. In other words, in some embodiments, a top surface 231 of the package body 23 is aligned (e.g., substantially coplanar) with the backside surface 211 a or 211 b of one or more of the passive components 21 a, 21 b. A lateral surface 232 of the package body 23 is aligned with the lateral surface 202 of the substrate 20; for example, the lateral surface 232 of the package body 23 is substantially coplanar with the lateral surface 202 of the substrate 20. In some embodiments, the package body 23 includes an epoxy resin having fillers dispersed therein.

The package body 24 is disposed on a portion of the top surface 231 of the package body 23 and over the passive components 21 a, 21 b to cover the passive components 21 a, 21 b. The package body 24 is not disposed over the active component 22. In some embodiments, a distance from a top surface 241 of the package body 24 to the backside surface 211 a or 211 b (e.g., top surfaces) of one or more of the passive components 21 a, 21 b is in a range from about 50 μm to about 100 μm. A thickness of the package body 24 (e.g., a distance from the top surface 241 of the package body 24 to the top surface 231 of the package body 23) is determined according to a thickness difference between the active component 22 and the passive components 21 a, 21 b. In some embodiments, an area of the package body 24 is greater than an area of each of the passive components 21 a, 21 b. In some embodiments, the package body 24 comprises, or is formed from, a photosensitive material, such as a photopolymer resin. In some embodiments, the package body 24 and the package body 23 comprise a same material. Alternatively, the package body 24 and the package body 23 may comprise different materials. In some embodiments, the top surface 241 of the package body 24 is higher than the top surface 231 of the package body 24. For example, a first distance may be between the top surface 241 of the package body 24 and the top surface 201 of the substrate 20, and a second distance may be between the top surface 231 of the package body 23 and the top surface 201 of the substrate 20, and the first distance may be greater than the second distance.

The shielding layer 25 is disposed on external surfaces of the package body 23 and the package body 24 to cover the package body 23, the package body 24, the active component 22 and lateral surfaces 202 of the substrate 20. The shielding layer 25 is electrically connected to the grounding element of the substrate 20. In some embodiments, the shielding layer 25 is a conformal shield. In some embodiments, a thickness of the shielding layer 25 is substantially uniform. A bottom of the shielding layer 25 is aligned with a bottom surface 203 of the substrate 20; for example the bottom of the shielding layer 25 may be substantially coplanar with a bottom surface 203 of the substrate 20. In some embodiments, the shielding layer 25 is a conductive thin film, and may include, for example, Al, Cu, Cr, Sn, Au, Ag, Ni or stainless steel, or a mixture, an alloy, or other combination thereof. The shielding layer 25 may include a single conductive layer or multiple conductive layers. In some embodiments, the shielding layer 25 includes multiple conductive layers, and the multiple conductive layers may include a same material, or ones of the multiple conductive layers may include different materials, or each of the multiple conductive layers may include different materials from others of the multiple conductive layers. In some embodiments, each conductive layer of the shielding layer 25 has a thickness of up to about 200 μm, such as up to about 150 μm, up to about 100 μm, up to about 50 μm, up to about 10 μm, up to about 5 μm, up to about 1 μm, or up to about 500 nm. In some embodiments, each conductive layer of the shielding layer 25 has a thickness of down to about 100 nm or less, down to about 50 nm or less, or down to about 10 nm or less. In some embodiments, the shielding layer 25 includes multiple conductive layers, and the different conductive layers may have different thicknesses.

As stated above, since an additional package body (e.g., the package body 24) is disposed over the passive components 21 a, 21 b to increase the mold clearance, the parasitic capacitance effect due to insufficient mold clearance may be reduced. Therefore, the accuracy of the passive components 21 a, 21 b may increase and then insertion loss and return loss of a filter formed by the passive components 21 a, 21 b may be well controlled.

FIGS. 3A-3D illustrate a semiconductor manufacturing method in accordance with some embodiments of the present disclosure.

Referring to FIG. 3A, a substrate strip including multiple substrates 30 is provided, and the provision of the multiple substrates 30 allows multiple semiconductor package devices to be manufactured concurrently. The substrate 30 may be, for example, a printed circuit board, such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass-fiber-based copper foil laminate. The substrate 30 may include an interconnection structure, such as an RDL or a grounding element.

The passive components 31 a, 31 b are disposed on a top surface 301 of the substrate 30. The passive component 31 a, 31 b may be an electronic component, such as a capacitor, a resistor or an inductor. Each passive component 31 a, 31 b may be electrically connected to one or more of another passive component 31 a, 31 b and to the substrate 30 (e.g., to the RDL), and electrical connection may be attained by way of SMT.

The active component 32 is disposed on the top surface 301 of the substrate 30. The active component 32 may be an electronic component, such as an IC chip or a die. The active component 32 may be electrically connected to one or more of the passive electrical components 31 a, 31 b and to the substrate 30 (e.g., to the RDL), and electrical connection may be attained by way of flip-chip or wire-bond techniques. In some embodiments, a height of the active component 32 measured from the top surface 301 of the substrate 30 is greater than those of the passive components 31 a, 31 b. Alternatively, the height of the active component 32 may be less than that of at least one of the passive components 31 a, 31 b. In some embodiments, the active component 32 is referred to as a first electronic component and the passive component 31 a and/or 31 b is referred to as a second electronic component.

A package body 33 is formed on the top surface 301 of the substrate 30 and encapsulates a part of the top surface 301 of the substrate 30, the passive components 31 a, 31 b and a part of the active component 32. A backside surface 321 of the active component 32 is exposed from the package body 33. In other words, the backside surface 321 of the active component 32 is aligned with a top surface 331 of the package body 33; for example, the backside surface 321 of the active component 32 is substantially coplanar with the top surface 331 of the package body 33. A lateral surface 332 of the package body 33 is aligned with a lateral surface 302 of the substrate 30; for example, the lateral surface 332 of the package body 33 is substantially coplanar with the lateral surface 302 of the substrate 30. In some embodiments, the package body 33 includes an epoxy resin having fillers dispersed therein. The package body 33 may be formed by a molding technique, such as transfer molding or compression molding.

Referring to FIG. 3B, a package body 34 is formed on a portion of the top surface 331 of the package body 33 and over the passive components 31 a, 31 b. The package body 34 is not formed over the active component 32. In some embodiments, the package body 34 can be formed by the following operations: (i) coating a photosensitive material, such as a photopolymer resin on the top surface 331 of the package body 33 and over the passive components 31 a, 31 b; and (ii) curing the photosensitive material by ultra violet (UV) light. In operation (i), the coating can be accomplished by spraying. In some embodiments, a distance from a top surface 341 of the package body 34 to the backside surface 311 a or 311 b (e.g., top surfaces) of one or more of the passive components 31 a, 31 b is in a range from about 50 μm to about 100. A thickness of the package body 34 (e.g., a distance from the top surface 341 of the package body 34 to the top surface 331 of the package body 33) is determined according to a thickness difference between the active component 32 and the passive components 31 a, 31 b. In some embodiments, an area of the package body 34 is greater than an area of each of the passive components 31 a, 31 b. In some embodiments, the package body 34 and the package body 33 comprise a same material. Alternatively, the package body 34 and the package body 33 may comprise different materials. In some embodiments, the top surface 341 of the package body 34 is higher than the top surface 331 of the package body 33. For example, a first distance may be between the top surface 341 of the package body 34 and the top surface 301 of the substrate 30, and a second distance may be between the top surface 331 of the package body 33 and the top surface 301 of the substrate 30, and the first distance may be greater than the second distance. In some embodiments, the package body 33 is referred to as a first package body 33 and the package body 34 is referred to as a second package body 34. In some embodiments, a package body includes a first portion 33 of the package body and a second portion 34 of the package body.

Referring to FIG. 3C, singulation may be performed to separate out individual semiconductor package devices. That is, the singulation is performed through the package body 33 and the substrate strip including the substrates 30. The singulation may be performed, for example, by using a dicing saw, laser or other appropriate cutting technique.

Referring to FIG. 3D, a shielding layer 35 is formed to cover the exterior surface of the package body 33, the package body 34 and a lateral surface 302 of the substrate 30. In some embodiments, the shielding layer 35 is a conformal shield. In some embodiments, a thickness of the shielding layer 35 is substantially uniform. A bottom of the shielding layer 35 is aligned with a bottom surface 303 of the substrate 30; for example, the bottom of the shielding layer 35 is substantially coplanar with the bottom surface 303 of the substrate 30. In some embodiments, the shielding layer 35 can be formed by sputtering or other appropriate technique. In some embodiments, the shielding layer 35 is a conductive thin film, and may include, for example, Al, Cu, Cr, Sn, Au, Ag, Ni or stainless steel, or a mixture, an alloy, or other combination thereof.

The shielding layer 35 may include a single conductive layer or multiple conductive layers. In some embodiments, the shielding layer 35 includes multiple conductive layers, and the multiple conductive layers may include a same material, or ones of the multiple conductive layers may include different materials, or each of the multiple conductive layers may include different materials from others of the multiple conductive layers. In some embodiments, each conductive layer of the shielding layer 35 has a thickness of up to about 200 μm, such as up to about 150 μm, up to about 100 μm, up to about 50 μm, up to about 10 μm, up to about 5 μm, up to about 1 μm, or up to about 500 nm. In some embodiments, each conductive layer of the shielding layer 35 has a thickness of down to about 100 nm or less, down to about 50 nm or less, or down to about 10 nm or less. In some embodiments, the shielding layer 35 includes multiple conductive layers, and the different conductive layers may have different thicknesses.

In the operation shown in FIG. 3B, the package body 34 is additionally formed over the passive components 31 a, 31 b to increase the mold clearance, so the parasitic capacitance effect due to insufficient mold clearance may be reduced. Therefore, the accuracy of the passive components 31 a, 31 b may increase and then insertion loss and return loss of a filter formed by the passive components 31 a, 31 b may be well controlled.

As used herein, the terms “substantially,” “substantial,” “approximately,” and “about” are used to denote and account for small variations. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation of less than or equal to ±10% of that numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. As another example, a thickness of a film or a layer being “substantially uniform” can refer to a standard deviation of less than or equal to ±10% of an average thickness of the film or the layer, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. The term “substantially coplanar” can refer to two surfaces within μm of lying along a same plane, such as within 40 μm within 30 μm within 20 μm within 10 μm or within 1 μm of lying along the same plane. Two surfaces or components can be deemed to be “substantially perpendicular” if an angle therebetween is, for example, 90°±10°, such as ±5°, ±4°, ±3°, ±2°, ±1°, ±0.5°, ±0.1°, or ±0.05°. When used in conjunction with an event or circumstance, the terms “substantially,” “substantial,” “approximately,” and “about” can refer to instances in which the event or circumstance occurs precisely, as well as instances in which the event or circumstance occurs to a close approximation.

In the description of some embodiments, a component provided “on” another component can encompass cases where the former component is directly on (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component.

Additionally, amounts, ratios, and other numerical values are sometimes presented herein in a range format. It can be understood that such range formats are used for convenience and brevity, and should be understood flexibly to include not only numerical values explicitly specified as limits of a range, but also all individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly specified.
